Just a quick compatibility update for changes in 1.17, with a few bonuses. Most new blocks and mobs are still missing.

NEW STUFF
* Added Beds: 16 different variations in style, not just the same bed with different colors.
* Added Calcite, Deepslate, Dripstone Block (but not pointed dripstones).
* Added Rooted Dirt.

TWEAKS
* Re-designed Stone, Sandstone, Granite and Andesite in order to make them more realistic, more useful to build things with, and less of an eye-sore when spelunking. In particular, Stone is now much brighter (the Addendum pack "Bright Stone" is no longer needed), Sandstone is more colorful, Granite is much more weathered before polishing, and Andesite is noisier and darker in order to finally have a dark stone for decoration less gray than Deepslate.
* Re-designed ores so they're no longer inclusion in stone but their own full-block mineral, in order to make prospection more realistic, and add decoration possibilities: banded hematite/magnetite for Iron, anthracite for Coal, kimberlite for Diamond, schist for Emerald, lapis rock for Lapis Lazuli, cuprite for Redstone, quartzite for Gold, malachite for Copper.
* New medieval design for Chiseled Stone Bricks.
* Brighter and wavy-er Red Sand.
* Brighter Hay Block.
* New design for Ice, brighter Packed Ice.
* New leafy Sugar Cane with random variations.
* New, more realistic Dandelion.
* Farm animals (Chicken, Pig, Sheep and Cow) now look like their wild counterparts (jungle fowl, boar, wild sheep and bison), so the Addendum pack "Untamed" is no longer included.
* Stained Glass now have frames, so the Addendum pack "Framed Glass" is no longer included. 
* Removed numbers from container GUIs, and also the Addendum pack "Unbound" that did the same.
* Removed my custom font because I have no idea how to make one with the new font system.
* Wool blocks are decorated with textile motifs instead of flat colors (similar to beds of the same color).
* New rain texture.
* Water is now blue AF and biome colors no longer change randomly depending on altitude. Thanks Mojang for that, but see below.

OPTIFINE ONLY
* Fixed lighting at dawn/sunset being too dark, and made it more colorful.
* Fixed water colors being too loud after changes brought by the Update Aquatic.
